Wow, this was a fantastic story, and I'm only on the furthest edge of Bat-fandom (I liked the comics way back when, and the most recent animated show. Plus, *cough*, the Biff Pow! tv show, which included a massive crush on the Riddler. No, I don't know why either.) I've always liked Barbara Gordon, and I liked this fic very muchly as well.
Maybe There are Secret Places
